Well, of course there are some good listings there, but I would have selected others as we probably all would. Reference is made to Schubert's complete Impromptu sets. Rach3 mentions Brendel's, and my favourite interpretations by him appear on the Vox label (not so much the Philips). I believe even Brendel mentioned somewhere that he, himself, had a preference for the Vox recording. Brendel, of course, worked with legendary Edwin Fischer, himself, another great Schubertian. I don't believe he worked with Artur Schnabel (another great Schubertian) who produced a stunningly beautiful set of the Impromptus for EMI. Insofar as the Schubert Mass No. 6 in E-flat, my preference has always been for the one EMI recorded with Erich Leinsdorf that appears now on Testament. The soloists, and especially the St. Hedwig's Choir and Berlin Philharmonic Orchestra under Leinsdorf make it one of my favourite recordings. IMHO, Leinsdorf reached areas of inspiration in this music that I don't always find in other of his recordings.

.....AND, I agree with you about that Schubert/Leinsdorf Eb Mass, which I sang in Carnegie Hall with David Randolph in the 1970's. The Leinsdorf is one of my most cherished recordings, recently issued on Testament.

Performances apart, the repertoire is strange. All nine symphonies? All those overtures? All the music for solo violin and piano? Hardly "essential." Only the last three piano sonatas? Hardly any of the individual songs? And like Holden Fourth, I disagree with nearly all the chosen recordings.
